Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
In the description of the present invention, it should be noted that term " on ", "lower", "inner", "outside" " front end ", " rear end ",
The orientation or positional relationship of the instructions such as " both ends ", " one end ", " other end " is to be based on the orientation or positional relationship shown in the drawings, only
It is that for the convenience of describing the present invention and simplifying the description, rather than the device or element of indication or suggestion meaning must have specifically
Orientation is constructed and operated in a specific orientation, therefore is not considered as limiting the invention.In addition, term " first ", " the
Two " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation " " is set
Be equipped with ", " connection " etc., shall be understood in a broad sense, such as " connection ", may be a fixed connection, may be a detachable connection or one
Connect to body；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, it can also be indirect by intermediary
It is connected, can be the connection inside two elements.For the ordinary skill in the art, on being understood with concrete condition
State the concrete meaning of term in the present invention.
As shown in Figure 1-3, a kind of elbow for reducing local resistance loss, including shell 1, one end of shell 1 are fixedly mounted
There is upper connecting flange 2, the other end of shell 1 is fixedly installed with lower connecting flange 3, the top surface edge position of upper connecting flange 2
